The new 13-inch and 15-inch MacBook Pro models received beefier specs in the form of the Ivy Bridge processor, higher-end graphics, and more hard drive options. The screen resolution remains the same, as do the prices.

The Retina Display offers a resolution of 2,880 x 1,800 pixels, considered the highest resolution on the market, certainly among 15-inch notebooks.

The new MacBook Pro is also thinner, measuring less than three-quarters of an inch in height. Add to that such options as an Ivy Bridge Core i7 processor, high-end graphics, up to 16GB of memory, and a speedy 768GB solid-state drive, and you've got a laptop that sells for anywhere from $2,199 to $2,799.
